Kashin the elephant may be joining the ranks of Vincent Van Gogh and Claude Monet - artists whose work became more popular after death.
The widely adored Auckland zoo elephant, who died five years ago, painted an oil on canvas with her lifelong friend, an Asian elephant called Burma.
The painting is expected to bring up to $3000 at an auction of contemporary and modern art in Auckland on Thursday.
Kashin and Burma were best friends at Auckland Zoo and painted by holding brushes with their trunks in 2007, two years before 40-year-old Kashin was euthanised because of deteriorating health.
The painting had previously been held in a private collection and is now on the market.
Richard Thomson, director of the International Art Centre in Parnell, said Kashin's personality had touched zoo visitors.
"She really was a very special part of Auckland and that is reflected by the great interest we have seen in this work."
Another work in Thursday's sale is Red Haring, an oil on canvas painted by Dick Frizzell in 2008, which is expected to go for $65,000.
